- IaaS basically offers storage facility which allows users to host their data in a remote location.
- In SaaS model cloud based applications are hosted in the service provider’s location and available to the users over the internet.
- PaaS combines the features of both. In this model hardware, OS, storage and network capacity are offered to the user through internet connectivity.
Paas cloud based technology can be regarded as an extension of the SaaS model where both software and infrastructure are made available to users. Users can rent server space in provider’s virtualized environment to create, test, deploy and host applications. As a result, it offers several benefits to developers and developing teams spread across different geographical locations.
Obviously a question arises about entrepreneurial benefits of using PaaS cloud based technology for enterprises. It is increasingly becoming a preferred choice for organizations that like to develop a private cloud for themselves.
As cloud in undergoing evolution, PaaS too is changing to become more sophisticated and aligned towards the needs of users. Even today most PaaS cloud based services are offered by third-party hosting service, wherein applications are developed and deployed through a third-party virtualized interface. But the future seems to be more in favor of open source environment where the PaaS will be a mixture of all three – public, private and hybrid cloud set-ups.
